Description
Cintas adhesivas.Adhesive tapes.
El invento trata del desarrollo de cintas adhesivas exentas de resina adhesiva con sistemas de composición cohesivos en base a látices de estireno/butadina con un elevado contenido de butadina y látex de caucho natural.The invention is about the development of tapes adhesives free of adhesive resin with composition systems cohesives based on styrene / butadine latex with a high Butadine and natural rubber latex content.
Los sistemas clásicos de composición adhesiva para cintas adhesivas se basan generalmente en el caucho natural, en copolímeros en bloque de estireno y en poliacrilatos. Para aplicaciones en las que se requieren exigencias especiales de un comportamiento reversible, se puede emplear también acetato etilvinílico o polisobutileno.The classic adhesive composition systems for adhesive tapes are usually based on natural rubber, in styrene block copolymers and in polyacrylates. For applications where special requirements of a reversible behavior, acetate can also be used ethyl vinyl or polyisobutylene.
Látices de estireno/butadina se emplean desde hace años en el sector "Pressure Sensitive Adhesives" para impregnar y estabilizar materiales de soporte. En este caso, están en primera línea, papeles, géneros, y telas sin tejer. La impregnación o el recubrimiento no deben ser pegajosos en ningún caso debido a la aplicación. Los copolímeros de estireno/butadina empleados para esta aplicación deben contener por lo tanto un elevado porcentaje de monómeros endurecedores, pero por otro lado, también monómero ablandador suficiente, de modo que el copolímero sea aún flexible. Látices de estireno/butadina con un contenido de butadina en torno al 25-55% cumplen esta exigencia con holgura. Films en base a estos copolímeros, son medianamente elásticos hasta elásticos y no adhesivos, dependiendo del contenido en butadina. Este tipo de copolímeros existen en el mercado de materias primas desde hace muchos años (Tipos de Butofan^{R} de BASF, diversos tipos de Dow y de Synthomer). Dependiendo de su fabricación, este tipo de látices o dispersiones contienen sistemas emulsionantes para generar compatibilidad entre la fase orgánica y la acuosa.Styrene / butadine latices are used since years ago in the "Pressure Sensitive Adhesives" sector for impregnate and stabilize support materials. In this case, they are in the front line, papers, genres, and nonwovens. The impregnation or coating should not be sticky in any case due to application. Styrene / Butadine Copolymers employees for this application must therefore contain a high percentage of hardener monomers, but on the other hand, also sufficient softening monomer, so that the copolymer Be still flexible. Styrene / butadine latices with a content of Butadine around 25-55% meet this requirement Loosely Films based on these copolymers, are moderately elastic to elastic and non-adhesive, depending on the content in butadine This type of copolymers exist in the market of Raw materials for many years (Types of Butofan R of BASF, different types of Dow and Synthomer). Depending on your manufacturing, this type of latices or dispersions contain systems emulsifiers to generate compatibility between the organic phase and the watery
Los copolímeros de estireno/butadina se utilizaron en el pasado también como polímeros base para composiciones de etiquetas. En el sector de las etiquetas se añaden frecuentemente a la cohesión significados secundarios, de modo que sistemas débiles adhesivos, tras la composición con resinas fijadoras comunes (dispersiones de resina) muestran en muchos casos las características suficientes.The styrene / butadine copolymers are used in the past also as base polymers for Label compositions In the sector of the labels are added frequently to cohesion secondary meanings, so that weak adhesive systems, after resin composition common fixatives (resin dispersions) show in many cases enough features.
Los copolímeros de estireno/butadina se describieron también en combinación con látices de caucho natural. Un resumen al respecto se encuentra en: Donatas Satas, Handbook of Pressure Sensitive Adhesive technology, 3 Edition, Natural Rubber Adhesives by G. L. Butler (pág. 276-283).The styrene / butadine copolymers are They also described in combination with natural rubber latices. A summary on this is found in: Donatas Satas, Handbook of Pressure Sensitive Adhesive technology, 3 Edition, Natural Rubber Adhesives by G. L. Butler (p. 276-283).
Osari describe en la patente EP-A1-688 843 la aplicación de emulsiones acuosas en base a látex de caucho natural para la fabricación de cintas adhesivas. El aditivo de dispersiones de estireno/butadina con un contenido usual de aproximadamente 25-55% sirve en este caso, fundamentalmente para la estabilización del látex de caucho natural de cizallamiento inestable y para el ajuste de la viscosidad.Osari described in the patent EP-A1-688 843 the application of aqueous emulsions based on natural rubber latex for manufacture of adhesive tapes. The dispersion additive of styrene / butadine with a usual content of approximately 25-55% serves in this case, mainly for the shear rubber latex stabilization unstable and for viscosity adjustment.
Como polímeros de revestimiento para composiciones adhesivas cohesivas los copolímeros usuales de estireno/butadina con un contenido de entre 25 y 55% son poco apropiados, ya que éstos deben ser convertidos siempre en adhesivos, usando considerables cantidades de resina de fijación, lo cual está unido a una considerable pérdida de cohesión. Este procedimiento excluye la aplicación para cintas adhesivas, para lo que se necesitan composiciones adhesivas cohesivas.As coating polymers for cohesive adhesive compositions the usual copolymers of styrene / butadine with a content of between 25 and 55% are little appropriate, since these must always be converted into adhesives, using considerable amounts of fixing resin, which is together with a considerable loss of cohesion. This procedure excludes the application for adhesive tapes, for which They need cohesive adhesive compositions.
Los copolímeros de estireno/butadina son básicamente interesantes como polímeros de revestimiento para composiciones adhesivas exigentes, debido a la estructura polímera y al nivel de precio.Styrene / butadine copolymers are basically interesting as coating polymers for demanding adhesive compositions, due to the polymer structure and at the price level.
El objetivo del invento en este caso era conseguir ayuda y poner a disposición una composición adhesiva en base a estireno/butadina que no contenga la carencia de la baja cohesión y con la cual se pueda fabricar una cinta adhesiva que también pueda ser utilizada para aplicaciones reversibles.The aim of the invention in this case was get help and make available an adhesive composition in styrene / butadine base that does not contain the lack of loss cohesion and with which you can make an adhesive tape that It can also be used for reversible applications.
Este objetivo se solucionó aplicando una dispersión de estireno/butadina exenta de resina con un elevado contenido de butadina y mezclada con látex de caucho natural. A la composición resultante de este modo se pueden añadir, de ser necesario, otros coagentes, por ejemplo, agentes de protección contra el envejecimiento o contra los rayos UV, materiales de relleno o emulgadores para adaptar la protección contra el envejecimiento y los datos técnicos adhesivos. Tras el recubrimiento de la composición adhesiva sobre un soporte de un papel o de un polímero, se consigue una cinta adhesiva según los requerimientos que satisfacen las exigencias de una cinta adhesiva con características cohesivas y que es apta por ejemplo, para aplicaciones reversibles. Este tipo de productos se pueden emplear por ejemplo en el sector de la protección de superficies. Además, se evitan influencias negativas sobre la cohesión de las composiciones adhesivas a causa de resinas adhesivas. Durante el proceso de desprendimiento se evitan también residuos de la resina adhesiva.This objective was solved by applying a resin-free styrene / butadine dispersion with high Butadine content and mixed with natural rubber latex. To composition resulting in this way can be added, if necessary, other co-agents, for example, protective agents against aging or against UV rays, materials filler or emulsifiers to adapt protection against Aging and adhesive technical data. Behind the coating of the adhesive composition on a support of a paper or a polymer, you get an adhesive tape according to the requirements that meet the requirements of an adhesive tape with cohesive characteristics and that is suitable for example for reversible applications. This type of products can be used for example in the area of surface protection. Also I know avoid negative influences on the cohesion of the compositions adhesives due to adhesive resins. During the process of detachment also prevents resin residues adhesive
La homopolimerización de estireno en un medio acuoso suministra polímeros que debido a su elevado Tg tiene un significado limitado para aplicaciones de pinturas. La copolimerización de estireno con un porcentaje aproximado del 35-45% de butadina en un medio acuoso suministra copolímeros capaces de unir films y en los que se puede lograr una temperatura mínima de conformación de films de aproximadamente 0ºC, de modo que estos sistemas pueden encontrar aplicación en los sectores de la imprimación, de la pintura, de los aglutinantes y de las modificaciones en general. Las dispersiones de etireno/butadina se estabilizan generalmente mediante la adición de pequeñas cantidades de grupos que contienen carboxilo, lo cual mejora simultáneamente la adherencia sobre diversas bases. Como composiciones adhesivas se pueden utilizar especialmente dispersiones copolímeras de estireno/butadina carboxilada con un contenido de butadina de 55-95%, preferentemente de 60-85%, respecto al material sólido total de estireno y butadina, que mezclado con látex de caucho natural revelan una excelente idoneidad como composición adhesiva para cintas adhesivas reversibles. Este tipo de copolímeros carboxilados contienen especialmente menos del 10%, preferentemente menos del 5% de comonómeros carboxilados respecto al contenido de monómeros, especialmente ácido acrílico en copolímeros.Homopolymerization of styrene in a medium aqueous supplies polymers that due to its high Tg has a limited meaning for paint applications. The copolymerization of styrene with an approximate percentage of 35-45% butadine in an aqueous medium supplies copolymers capable of joining films and in which a minimum film forming temperature of approximately 0 ° C, so that these systems can find application in the sectors of the primer, paint, binders and the modifications in general. Ethylene / Butadine Dispersions they are generally stabilized by adding small amounts of carboxyl-containing groups, which improves Simultaneously adhesion on various bases. How adhesive compositions can be used especially copolymer dispersions of styrene / carboxylated butadine with a butadine content of 55-95%, preferably of 60-85%, with respect to the total solid material of styrene and butadine, which mixed with natural rubber latex reveal excellent suitability as an adhesive composition for reversible adhesive tapes. This type of carboxylated copolymers they contain especially less than 10%, preferably less than 5% of carboxylated comonomers with respect to the content of monomers, especially acrylic acid in copolymers.
Los tipos de dispersiones de estireno/butadina según el invento con un contenido de >60% de butadina se pueden conseguir por ejemplo de la firma Dow.The types of styrene / butadine dispersions according to the invention with a content of> 60% butadine can be get for example from the Dow firm.
Los componentes de látex de caucho natural puede ser tanto látices del tipo de amoniaco bajo "low ammonia" como del tipo de amoniaco alto "high ammonia". Respecto al contenido de material sólido en total de copolímero de estireno/butadina y de látex de caucho natural, el porcentaje de caucho natural debería fluctuar entre 5 y 80%, preferentemente entre 20 y 50%. Para la determinación precisa de las características técnicas adhesivas se pueden utilizar también mezclas de diferentes látices de caucho natural. Para mejorar el comportamiento de envejecimiento se pueden emplear dispersiones de agentes de protección contra el envejecimiento y contra los rayos ultravioletas (UV) usuales que son suficientemente conocidos del sector de los elastómeros.The natural rubber latex components can be both ammonia-type "low ammonia" as long as of the type of high ammonia "high ammonia". Regarding the content of solid material in total of styrene / butadine copolymer and of natural rubber latex, the percentage of natural rubber should fluctuate between 5 and 80%, preferably between 20 and 50%. For the precise determination of the technical adhesive characteristics is they can also use mixtures of different rubber whips natural. To improve aging behavior, you can use dispersions of protective agents against aging and against the usual ultraviolet (UV) rays that They are sufficiently known in the elastomer sector.
Además, según la necesidad se pueden añadir otros aditivos para la adaptación de las características del producto, por ejemplo, materiales de relleno o emulgadores, por ejemplo, del tipo de alquifenoles alcoxilados. Mediante estos aditivos se consigue seguir influyendo sobre las características técnicas adhesivas de la manera deseada. La regulación del balance de adhesión/cohesión se puede realizar en caso de necesidad, mediante la reticulación química a través de los grupos carboxílicos existentes a través de agentes reticulantes adicionales, por ejemplo, quelato de aluminio o de titanio.In addition, according to the need can be added other additives for adapting the characteristics of the product, for example, fillers or emulsifiers, by example, of the type of alkoxylated aliphenols. Through these additives can continue to influence the characteristics Adhesive techniques in the desired way. Balance regulation of adhesion / cohesion can be carried out if necessary, by chemical crosslinking through the groups existing carboxylic acids through crosslinking agents additional, for example, aluminum or titanium chelate.
La aplicación del compuesto adhesivo es de 10-120g/m^{2}, preferentemente de 15-40g/ m^{2}.The application of the adhesive compound is of 10-120g / m2, preferably of 15-40g / m2.

Los espesores de los films son de 10 a 250 \mum, preferentemente entre 20 y 120 \mum.The thicknesses of the films are from 10 to 250 µm, preferably between 20 and 120 µm.
Para garantizar la adherencia de la composición adhesiva sobre el material de soporte la energía de la superficie de la cara a cubrir debe estar dentro del segmento definido. Esto se puede garantizar ya sea mediante una capa adicional de imprimación o mediante un tratamiento de superficie. Preferentemente se aplica un pre-tratamiento de llama o de corona con el que se pueden conseguir las energías de superficie deseadas. Las energías de superficies deberían estar en un rango de 25-50 mN/m, preferentemente de 30-45 mN/m.To ensure the adhesion of the composition adhesive on the support material surface energy of the face to be covered must be within the defined segment. This is can guarantee either by an additional layer of primer or by a surface treatment. It preferably applies a pre-treatment of flame or crown with which the desired surface energies can be achieved. The surface energies should be in a range of 25-50 mN / m, preferably 30-45 mN / m.
Como materiales de soporte se pueden considerar además, papeles cresponados definidos e impregnados y altamente encolados, resistentes a la rotura que satisfacen las exigencias deseadas. Dependiendo de la aplicación deseada se pueden utilizar papeles con una mayor capacidad de extensión longitudinal como capacidad de extensión transversal, como también papeles con mayor capacidad de extensión transversal como capacidad de extensión longitudinal, tanto en versión blanqueada como en la versión ecológica sin blanquear.As support materials can be considered in addition, defined and impregnated and highly matched papers glued, resistant to breakage that meet the requirements desired. Depending on the desired application can be used papers with a greater capacity of longitudinal extension as transversal extension capacity, as well as papers with greater transverse extension capacity as extension capacity longitudinal, both bleached version and version Organic unbleached.
